any of the guns I own could shoot a depleted uranium bullet as long as it was the correct caliber.

And automatic weapons are not illegal to own. But tell me, if you can, when was the last time a crime was committed with a legally purchased automatic weapon.

They are, unless you have a class III license and are a dealer (using it for demonstration purposes) Unless I'm incorrect on that.

I don't know the answer to your question, but I can tell you the majority of violent crime (according to FBI statistics) are with *gasp* firearms. Let's be clear here, no on (in this thread) is calling for the banning of weapons, I asking what can be done to minimize the risk of these weapons getting into the wrong hands? Of should we just ignore the problem?
